4. ASSEMBLY
4.1. After unpacking, turn the machine so the back is facing (g.2).
4.1.1. Connect the 12v power cables to the positive(+) and negative(-) sockets.
4.1.2. Connect the smoke hose to the smoke output by removing the locking nut, slip the nut over the hose, push t the hose to the output
and then tighten the nut to hold the hose in place.
4.1.3. Connect the 12v power cables to the positive(+) and negative(-) terminals of a 12V car battery using the crocodile clips.
5. OPERATION
5.1. OPERATIONAL STEPS FOR AIR INTAKE SYSTEM TEST
5.1.1. Open the vehicles air filter cover and take out the air filter.
5.1.2. Take out the inflatable bladder from the accessory box and continue to squeeze it until the inflated diameter of the rubber bladder matches
the diameter of the air inlet.
5.1.3. Remove the oil filler cap (fig.1), add 10ml of test oil into it, and tighten the cap.
5.1.4. Press the air mode button and the smoke mode button respectively (fig.1).
5.1.5. Block the smoke/air nozzle and check that the gauge dial increases and is working correctly. Once pressure reaches 0.8kg/cm2 the check
is complete. Just press the Air Mode button for this test.
5.1.6. Connect smoke/air nozzle to the inflatable bladder.
5.1.7. The leak point of the air intake system can then be diagnosed by the escape of smoke/air. Reference the gauge to help diagnose the level
of leak.
5.2. AIR MODE - WHERE SMOKE IS NOT SUITABLE
5.2.1. Press Air Mode button only for this test (fig 1).
5.2.2. Allow the pressure to build. If you are testing a sealed unit then you would expect the gauge to read above 1kg/cm2. If there is a leak then
the gauge would not reach this level. Listen out for any air noises throughout the system referencing the gauge.
WARNING! It is not recommended to add more than 10ml of the test oil into the detector, otherwise it will cause the smoke generator to
stop working, smoke will not be generated and there is potential for an oil spill.
If the product is used for an excessive period of time, the internal temperature of the machine will rise and the overheat alarm light will
illuminate (g.1). Please disconnect the power supply immediately to stop device working and allow it to cool down.
It is not recommended to operate this product for more than 15 minutes at any one time.
5.3. SMOKE MODE
5.3.1. Press Smoke Mode button only for this test (g1).
5.3.2. Allow the pressure to build. If you are testing a sealed unit then you would expect the gauge to read above 1kg/cm2. If there is a leak
then the gauge would not reach this level. Listen out for any air noises throughout the system referencing the gauge. Smoke will help
further diagnose and locate the problem.
6. MAINTENANCE.
6.1. After the test, remove and clean the accessories. Then put them back into the box.
6.1.1. Remove the oil drain cap (g.2), drain the test oil out and pour it back into the oil bottle.
6.1.2. Clean the main unit and check if there is any fault, loose connection or damage.
6.1.3. After use of the main unit and the accessories, please keep them in a cool, dry and dust-free place.
6.1.4. Smoke and oil will oxidise and deteriorate after being in high temperature for a long time, which will aect the service life of the smoke
generator. Please change the test oil regularly.
